【Overview】

[] The ESP32 octal relay development board is equipped with the ESP32-WROOM-32E WiFi&BLE module, with all I/0 ports connected and supports DC5-30V power supply. It is suitable for ESP32 secondary development learning, smart home wireless control and other occasions.

【Features】

[] 1. The board has a mature and stable ESP32-WROOM-32E module with a large capacity of 4M Byte Flash;

[] 2. The I/O port and UART program download port of the ESP32 module are all brought out to facilitate secondary development;

[] 3. The power supply voltage is DC5V/7-30V;

[] 4. The board has 100 programmable buttons and a reset button for the ESP32 module;

[] 5. ESP32 supports the use of ArduinoIDE development tools and provides reference programs under the Arduino development environment;

[] 6. The board has 8 5V relays that output switch signals, suitable for controlling loads with a working voltage of less than AC250V/DC30V;

[] 7. There is 1 programmable LED and relay indicator on the board.

【Interface Introduction】

[] Burning port: ESP32's GND, RX, TX, 5V are connected to the GND, TX, RX, 5V of the external TTL serial port module respectively. When downloading, 100 needs to be connected to GND. After downloading is complete, disconnect 100 from GND.

[] Relay output terminal:

NC: Normally closed terminal, short-circuited with COM before the relay is energized, and left floating after energization;

COM: Common terminal;

NO: Normally open terminal, left floating before the relay is energized, and left short-circuited with COM after energization.
